Sam Acho’s preseason illness was mononucleosis, the Bears’ outside linebacker revealed to a radio show Wednesday night.
Acho told Laurence Holmes of WSCR-AM that he didn’t feel up to par during training camp, and he visited a doctor who told him the news.
“Long story short, they found out I had mono,” he said.
His liver and spleen was enlarged as a result, he said. He missed 19 days before returning to the team.
Acho made his season debut Sunday against the Cardinals after being cut the day before the Packers opener and re-signed two days later.
“We needed somebody to play on special teams that week,” he said. “It was more of a one-day roster move.”
He said there was a “mutual understanding” that he would return to the team.
